and effective means whereby different kinds of information may be transmitted over a single line to a receiver. Another object comprises the provision of means for sending different kinds of information, in combination with means operating to establish different cyclical periods for the respective kinds of information to be transmitted.

The invention further comprises provisions for enabling the transmission of one kind of information to be completed if, at the time a cyclical period assigned to another kind of information is established, the transmission of the first mentioned information has not been completed. In this connection means are also provided for preventing the transmission of one kind of information while another kind is being transmitted. Another object is to provide means for indicating to an operator the establishing of .the respective periods for transmission of the different kinds of information.

A further object is the provision of means for effectively supervising the continuity and condition of the transmission line and for providing an indication if failure of said line should occur.

Another feature of the invention resides in the provision of novel receiving means, including novel apparatus for recording the types of information transmitted. Included in this phase of the invention are novel provisions for driving a recording chart in either of opposite directions, for maintaining appropriate tension on the chart for bringing fresh portions of a chart into record-receiving position, and for effecting orientation of charts at different receiving stations.

More specific features of the invention comprise novel provisions whereby changes in the average prices of a group of stocks, bonds, or

averages, so that an observer may be apprised continuously of the trend of the market.

A further feature of the invention resides in novel and efllcient means for correlating the transmission of averages and volumes, enabling each to be transmitted at given times over the transmitting line without interference with the other. Novel means for transmitting impulses to the average recorder upon the accumulation of a predetermined change in average, while excluding changes below a predetermined amount, are also provided.

Further features of the invention will be described in the specification and pointed out in the appended claims.

The average transmitter The average transmitter I0 (Figures 3-13) comprises a given number of counters II each of which may be of the well known Veeder type, and each serving to indicate the present value of one of a selected group of stocks. The lowest indication on each counter may conveniently be chosen as /3 of a dollar.

Each of the stock counters ii is provided with a gear I2 and a push button I3. Depression of the button I3 engages an intermediate gear I4, associated with the particular counter, with the gear I2 of said counter. This may be conveniently accomplished as follows:

The intermediate gear I4 of each counter is mounted on a shaft I5 (Figures 3 and 5) slidably supported in a bracket I6. A spring I1, positioned between one end of said bracket and a collar I8 on said shaft I5 normally maintains the shaft I5 retracted, with the gear I'4 out of mesh with the associated gear I2 of the counter. At its end opposite the gear I4, shaft I5 is adapted to be engaged by a stud IS on a bail 20 piv- .est the shaft 25.

oted at 2| to a suitable bracket 22. Normally, under the action of the spring I'I, the shaft I I and bail 20 occupy the positions shown in Fig. '7. The bail 20 is suitably connected with the push button I3, as by a pin 23, so that when said push button is depressed, said bail is rocked from the position shown in Figure '7 to that shown in Figure 5, with consequent pushing of the shaft I5 by stud is into the Figure 5 position, wherein gear I4 is brought into mesh with the counter gear I2. A collar 24 on shaft I5 may be provided to limit the'extent of movement of said shaft I5 by engagement with bracket I6, as shown in Figure 5. Upon release of push button I3 by the operator, the compressed spring I! restores the shaft I5, ball 20, and gear I4 to their normal positions, with gear I'l disengaged from gear I2. A spring I2 which bears against gear I2 prevents the latter from overrunning or being turned accidentally.

Extending across the transmitter Ill and transversely to the counters II is a main operating shaft, 25, to which is attached a disk 25 having a handle 26', outside the transmitter casing 21. The main operating shaft 25 is shown as having secured thereto a plurality of bevel pinions 23, each of which meshes with a corresponding bevel pinion 29 pinned to a corresponding shaft 30. Each shaft 30, as shown in Fig. 5, is mounted in a suitable bracket 3| and has secured thereto a pinion 3I, which meshes with a gear 32 secured to a shaft 33. Each shaft 33 extends longitudinally of the transmitter casing and cooperates with a plurality of stock counters. Thus, as shown in Figure 3, the shaft 33 nearest the handle 26 has fastened thereto a pinion 34 which is in constant mesh with the gears ll of the pair of counters II revealed by the broken away top plate of the transmitter nearest the shaft 25. If now the button I3 associated with either of these counters is depressed, the corresponding gear I4 is shifted, as above described, into ene sement with gear I2 of said counter, while remaining in mesh with the gear 34 of the shaft 533, as shown in connection with the counter bearing the reading 124.00 in Fig. 3. Then, upon turning the handle 26 in either direction through a given extent, the aforesaid counter gear I2 is rotated through a corresponding extent and direction, correspondingly operating said counter. The shaft 33 is also provided with similar gears 34 Fig. 3 for similarly operating the pairs of counters shown to the left of the counters near- Since the construction employed in conjunction with shaft 33 and the others of said counters is the same as that above described, it need not be here repeated. The second shaft 33, adjacent the shaft 33 specifically described above, is likewise provided with gears 34 for operating associated pairs of counters in the same manner as hereinbefore described. The third shaft 33 is shown cooperating with a single set of counters instead of with pairs of counters on opposite sides of said shaft, but, as will be apparent, the operation of the counters from the gears 34 on said third shaft 33 is accomplished in the same manner as described above, i. e., by simply depressing the push button I3 associated with the appropriate counter and turning the handle 26 in the desired direction and through the desired extent.

In the embodiment of the invention here specifically described it is assumed that twenty-live individual stock counters II are present, only fifteen, however, being actually shown in Fig. 3.
